In this chapter I'm going to tell you what Horcruxes are, not how to make them. So, a Horcrux is an object of which a witch or wizard puts part of there soul in. I must say though, in order to make one you have to kill someone. Killing shatters the soul. If you want to learn how to make a horcrux you should read: A Hand to Hand Guide to Making Horcruxes by Parker Lestrange. I hope this chapter helped you understand Horcruxes a little bit more.
